Alexa and Jordan, 10, of Moreno Valley, had already gotten their faces painted and were relaxing with their family before considering what else to get at Sunday’s food truck festival held at San Manuel Stadium.

Besides being fun and a way to escape triple-digit temperatures, the event had special significance because it benefitted the Childhood Cancer Foundation of Southern California, said Rachel Logan, their mother.

“We do have cancer in our family, so this is worth a drive,” Logan said.

Admission – $7 if bought the day of the event – and 15 percent of the proceeds from the food trucks went toward the foundation, said Stephanie Avila, an executive assistant.

Members of the San Bernardino Public Employees Association, which represents county employees, held a barbecue at the festival and gave all of the money they earned to the foundation.

“It’s a win-win – good food and a good cause,” Avila said.

Supporting local businesses is a third win, said Jamie Krider of Where’s The Fire Pizza.

“Until cities (in San Bernardino County) pass new regulations, it’s just events like this for us,” said Krider, an employee and daughter of the owner. “We’d like to work out a route, but until then the only place in this county where we are regularly is Redlands every Market Night.”

The Apple Valley-based WTF pizza truck covers the area from Las Vegas to San Diego, she said, while most of the other food trucks were based in other counties.

The county Board of Supervisors voted in June to allow food trucks to operate year-round at certain “events” if they pay an annual fee of $596. San Bernardino and Riverside counties are the only California counties where food trucks can’t operate freely.
